 the following-: 



Celerv Blight, Rust, or Sun-Scald {Cereospora apii [Fries.] ) The 

 first indication of this disease is the appearance of yellowish 

 spots on the leaves. These finally run together and turn the 

 entire leaves yellow and then brown. 



Treatment. Secure as healthful conditions as possible. 

 Where the slants are somewhat shaded, they are less liable 

 to the disease than if in the full sunlight. This disease is 

 especially bad in very dry locations. It is reported that the 

 Bordeaux mixture and other standard fungicides will entirely 

 prevent it. 



Leaf Blight [Septorid Petroselini var. apii.) All parts of the 

 celery plant except the roots are liable to the attacks of this 



fungous disease. Wa- 

 tery spots appear on 

 the stems and leaves, 

 which soon show small, 

 black dots. This dis- 

 ease may be spread by 

 the seeds, which are 

 likely to become infect- 

 ed. 



Treatment. The 

 first precaution is to 

 plant clean seed. That 

 which is spotted or 

 speckled with the black 

 spots of disease should 

 be avoided. In addi-

 plan to spray the young plants with Bordeaux mixture on the 

 first appearance of the disease. 



Varieties of Celery. The dwarf kinds are the best to grow; 

 the red kinds are of the best quality but do not take well in 

 the markets. For early marketing the White Plume is highly es- 

 teemed and is, probably, the most profitable variety for general 

 marketing. Its stalks and leaves are white without goingthrough 

 the bleaching process but are not of as good flavor as when 

 bleached. One of the best flavored as well as best keeping
